The FFmpeg Project proudly presents FFmpeg 2.5 "Bohr", just 2.5 months
after the release of 2.4. Since this wasn't a long time ago, the Changelog
is a bit short this time.
The most important thing in this release is the major version bump of the
libraries. This means that this release is neither ABI-compatible nor
fully API-compatible. But on the other hand it is aligned with the Libav
11 release series, and will as a result probably end up being maintained for
a long time.
As usual, if you have any question on this release or any FFmpeg related
topic, feel free to join us on the #ffmpeg IRC channel (on
irc.freenode.net).
